Precautions for abnormal phenomena in the use of deep groove ball bearing

2021-08-27

When inspecting the deep groove ball bearing removed during the regular maintenance and operation of bearing equipment and the replacement of peripheral parts, it is necessary to judge whether the secondary bearing parts can be reused and record the good or bad use. Also carefully investigate and record the removed bearings and appearance. In order to find out and investigate the remaining amount of lubricant, the bearing shall be well cleaned after sampling.
Secondly, check the raceway surface, rolling surface and mating surface of deep groove ball bearing and the wear state of cage for damage and abnormalities, especially observe the running track of raceway surface. Whether the bearing can be used again shall be determined after considering the degree of bearing damage, machine performance, importance, operating conditions, inspection cycle, etc.
According to the inspection results, if the bearing is damaged and abnormal, please find out the causes and formulate countermeasures according to the phenomenon of bearing damage. In addition, according to the inspection results, if there are the following defects, the bearing can no longer be used and needs to be replaced with a new bearing.
How to ensure the normal operation of deep groove ball bearing, how to make the bearing free of damage and make the bearing life longer. Now let me explain to you the precautions to ensure the reliable operation of the bearing, hoping to help you.
In general, the precautions for ensuring reliable operation of bearings are as follows:
1. Any one of the inner and outer rings, rolling elements and cage has cracks and fragments.
2. Any one of the inner and outer rings and rolling elements has peeling.
3. The raceway surface, retaining edge and rolling element are significantly jammed.
4. The cage is seriously worn or the rivet is loose.
5. The raceway surface and rolling element are rusty and scarred.
6. There are significant indentation and indentation on the rolling surface and rolling element.
7. There is creep on the inner diameter surface of the inner ring or the outer diameter of the outer ring.
8. Overheating and discoloration.
9. The sealing ring and dust cover of grease sealed bearing are seriously damaged.
